Plugin fails with base jre after 1.5.0_01 is removed from the system

Tested_Java_Release : 1.5.0-beta3 Build 58
Tested_Build : jre-1_5_0-beta3-windows-i586.exe
Tested_Build_Location : /net/koori.sfbay/p/jdk06/jdk/1.5.0/beta3/b58/bundles/windows-i586
Testted O/S : Windows 2000, WinXP PRO
Tested_ Browsers : NS7.0, MZ1.6, IE6.0

The problem is seeing with NS/MZ, not IE


Steps to Reproduce :
 --------------------
1. Install jre-1_5_0-beta3-windows-i586.exe from the above mentioned location
2. Make sure Java Plug-in is running successfully using version 1.5.0-beta3-b58 from the following location:
http://sqeweb/st1/plugin-home/mimetypes/pluginhtml-default
3. Redirect java.sun.com to our internal apache server (10.5.21.239)
4. Add the entry in registry SOFTWARE/Javasoft/javaupdate/Policy
"UpdateServletURL http://java.sun.com/webapps/update/1.5.0/map.xml"
5. Update base jre with 1.5.0_01 through Java Control Panel -> "Update" tab -> click on "Update Now" button.
6. Make sure Java Plug-in is running successfully using update version 1.5.0_01-beta3-b58
7. Uninstall 1.5.0_01 and try to invoke any applet from the location above

Plugin fails with message in the MZ/NS
"Click here to get plugin"

The applet should be loaded with base jre (1.5.0-beta3-b58) after 1.5.0_01 is removed

This problem is reproducible with b56 and b58
The problem is not seeing in b51

However, Plug-in is running successfully on IE6.0 for all releases above.
